### Pull
|
|
|
|
Use `Array.filter()` to pull out the values that are not needed.
|
|
Use `Array.length = 0` to mutate the passed in array by resetting it's length to zero.
|
|
Use `Array.push()` to re-populate the original array to equal the pulled values
|
|
|
|
```js
|
|
const pull = (arr, ...args) => {
|
|
let pulled = arr.filter((v, i) => args.indexOf(v) === -1);
|
|
arr.length = 0;
|
|
pulled.forEach(v => arr.push(v));
|
|
}
|
|
|
|
// let myArray = ['a', 'b', 'c', 'a', 'b', 'c'];
|
|
// pull(myArray, 'a', 'c');
|
|
// console.log(myArray) -> [ 'b', 'b' ]
|
|
|
|
// let test = ['4', '1', '1', '5', '4', '2'];
|
|
// pull(test, '4', '1');
|
|
// console.log(myArray) -> [ '5', '2' ]
|
|
```
